SCHELINGER A26-RS-WIFI2 Astronomical Time Switch, Wi-Fi, 1-Channel, 48-240V AC/DC, 16A, DIN Rail

The SCHELINGER A26-RS-WIFI2 is a modern astronomical time switch designed for precise control of lighting and electrical circuits based on sunrise and sunset times. With built-in Wi-Fi connectivity, it can be easily programmed and monitored via the F&F FManager mobile app. This single-channel device operates on a wide supply voltage range of 48-240V AC/DC and supports a maximum switching current of 16A (AC-1). Its compact 1-module DIN rail housing makes it ideal for installation in distribution boards.

Advantages

Automatic adjustment to daylight saving time and location-based astronomical scheduling eliminate the need for manual reprogramming. The device features a 6-year power reserve, ensuring settings are retained even during power outages. With up to 250 programmable events and multiple modes (astronomical, weekly, countdown, pulse), it offers exceptional flexibility for various applications.
